has v9 killed anyones card or rendered them temporarily (a few reboots) comatose?

are the spikes in power sync'd with the "donation" portion of the mining?

None of my cards were killed.

I'm running 6 cards (r9 380) with zalman 1250w platinum and other 3 cards ( r9 280x, 280 and 7950) with super flower 850w ( golden green) with no problems.

V9.0 has no stability issues! Your rigs do! Increase GPU voltage or lower clocks!

V9 has some MAJOR stability issues for at least some configurations.

I tried lowering clocks on the 7870 test rig I DOCUMENTED my issues with during fairly extensive testing in the main CLaymore V9 thread - doing so made NO change even when I got the card down to about 200 Mhz UNDERclock on core and 300 on mem (afterburner limits for that card) the ONLY change was that the hashrates reported got lower than what I reported in that thread.

I can't increase voltages as they're locked on that card (and they're at stock anyway).

Same card was highly stable back in the days I used it on Scrypt mining, and for all the MooWrapper/Dnet work I did between it's Scrypt days and it's ETH/ZEC days - both of those drove that card a LOT harder than ETH or ZEC do (as measured by the MUCH HIGHER POWER DRAW and higher operating temp at higher fan settings in both cases).

I've never played with the BIOS on that card in any way, so it's not a "bios issue".

Try mining on pools that support low difficult,

You wont have your cards at full usage at once on high difficult shares,
since low dif you grab and found

You wont have that hardcore mining 100% at time

Ex:

High Dif - 3-5 minutes intensive mining for 1 share - so you have all of your Gpu Full of job for 3-5 minute unstopable

Low Dif 5-15 seconds quick mining for 1 share - Grab and Send, you wont have full usage 100% of time

It is just a theory but i think it is valid

I'd recommend being very cautious when increasing voltage with V9, given the increased power use from spikes.

Same settings V8 vs V9 on my Fury Nitro (1140/550, -12mv), GPU CORE POWER:

V8: AVG 207W; MAX 274W

V9: AVG 210W; MAX 370W

Only a 3W difference in AVG, but a nearly 100W change in MAX. Big difference to begin with, and enormous in an multi-gpu setup.

(As it stands, undervolting to -96mv and reducing clock to 1110mhz saves me 40W on average V9 vs V8, but the MAX is higher in V9 even when significantly undervolting from V8 (283W vs 280W))

9 has some serious stability problems.

oh god. 8 was so much better than this. what happened?

I was experiencing same issues with V8 but with less rigs in total. V7 was way stable than v8 and v9

this actually helps

even a broken clock is correct two minutes out of every day

referring to the forums signal to noise ratio more rather than Preludes track record of course..

Here's today's testing results.
All my cards are RX480. After updating them to V9 couple rigs stopped working. All errors were the same:

Code:

GPU 0 hangs in openCL error

except the one:

Code:

warning: solutions buf overflow, 10 > 8

but first things firs, after playing around with clocks and memory I got the speed ~220h/s but card were overheating, so I resetted wattman settings, now they hash at ~182h/s but fans and temps are stable, but they were still freezing, then I switched to stock bios, after that everything is working fine. Lets see what will happen, I hope stock bios and stable memory/clock will solve the problem.
also wanted to mention 3x RX480 8G - 330watts from the wall on V8 and 345watts from the wall on V9

I use this: CHIEFTEC A80 750W PSU.
One card consumes 120w.

Check not average, but MAX power spending
You will be surprised when you will see 250W

It's interesting. Can you attach please a gpuz screenshot (with the max "GPU only power draw")?

There might be spikes, but it should be a problem for standard design cards. However, I am also experiencing this problem although I own RX480 ASUS Strix version using 8 pin power cable instead of 6 which is shipped on the standard design, and I also have a decent PSU which is Corsair 1200W (with gold certification) nevertheless, problem persists. Also -nofee 1 option is not helpful.

I have turned back to v8, and my system crashed again after 5 min. however, it was very stable on v8 till this time. Huh

How many rx480 card do you use in the rig?

You will have to reduce the frequency of the core. The cores are stressed more. So it is quite unstalbe at present.

-This is 6 380x Not the 4xx everyone is having problems. Just posting my results.

I have one of 9 down this morning but im not 100 percent sure that i didnt cause the issue. I just forgot to check after making some changes to hardware. Been up over 22 hours still using -i 8 as well.
